FastTech News, November 3rd: It seems that since a certain point in time, there has emerged a strange argument in the outside world, which is that producing electric vehicles is more environmentally friendly than producing fuel vehicles. However, this is actually incorrect.

The latest research by scientists from Duke University in the United States shows that during the initial manufacturing stage of electric vehicles, the carbon dioxide emissions are approximately 30% higher than those of fuel vehicles. The main reason for this is the mining of lithium ore required for batteries and the high emissions during the battery manufacturing process.

However, once electric vehicles start running, their emission advantages quickly become apparent. After traveling the same distance, it only takes two years for their carbon emissions to surpass those of fuel vehicles.

The research team used the Global Change Analysis Model (GCAM) to simulate four scenarios of electric vehicle adoption in the United States until 2050, and comprehensively analyzed emissions during the fuel production, battery manufacturing, vehicle assembly, and vehicle usage stages.

The results show that with the advancement of battery technology, by 2030, for every 1 kilowatt-hour increase in battery capacity, approximately 220 kilograms of carbon dioxide emissions can be reduced, and by 2050, the reduction will be approximately 127 kilograms.

In addition, the study also evaluated the combined impact of air pollution and climate change for different vehicle models. It is estimated that the economic losses caused by fuel vehicles during their 18-year lifespan (such as health expenses due to air pollution, etc.) are 2 to 3.5 times those of electric vehicles.

So, to sum up simply, the process of producing electric vehicles is not environmentally friendly, and their carbon emissions are higher than those of fuel vehicles. However, once they start running, their performance in this regard is much better.
